Note 2. All voltages with respect to ground.
Note 16. TVDDA must be connected to DVDD. The power-up sequence between AVDD, PVDD, SAVDD, DVDD,
TVDD2, TVDD3, AVDDA, TVDDA, SVDDA and PVDDA is not critical. However, the PDN and PDNA pin
must be held to “L” until all power supply pins are supplied. After all power supplies are filled, PDN and PDNA
pins should be set to “H”.
* The AK4675 supports the following two cases of partial power ON/OFF. In these cases, PDNA pin should be “L” and
all power management bits (PMVCM, PMMP, PMMICL, PMMICR, PMADL, PMADR, PMDAL, PMDAR, PMPLL,
PMLOOPL, PMLOOPR, PMAINL1, PMAINR1, PMAINL2, PMAINR2, PMAINL3, PMAINR3, PMAINL4,
PMAINR4, PMLO1, PMRO1, PMLO2S, PMRO2S, PMLO3, PMRO3, PMSRA, PMSRB, PMPCM, and PMSAD)
should be OFF or PDN and PDNA pins should be “L”.
1. DVDD=TVDDA=SVDDA=ON, AVDD=PVDD=SAVDD=TVDD2=TVDD3=AVDDA=PVDDA=OFF
2. DVDD=TVDDA=ON, AVDD=PVDD=SAVDD=TVDD2=TVDD3=AVDDA=PVDDA=SVDDA=OFF
When the power state is changed from OFF to ON in the above cases, the PDN and PDNA pins should be set to “H” after
all power supply pins are supplied.
When DVDD and TVDDA are powered OFF, AVDD, PVDD, SAVDD, TVDD2, TVDD3, AVDDA, TVDDA, SVDDA
or PVDDA must be powered OFF. When only DVDD and TVDDA are OFF, leak current of 10mA to 100mA may occur.
* AKEMD assumes no responsibility for the usage beyond the conditions in this datasheet.
